I had to move some rock around because I lost my clown goby. So a peppermint had him and I had to move alot of rock around but when I put one of the pieces in a bucket my 6 line wrasse fell into the bucket. We quickly got him back in the tank, he went straight to the back and I have not seen him for 2 days. Are these guys prone to hiding when scared ? I just did a big water change too and I figured the fish were under a little stress. I have 2 tangs that seem to be alright. Thanks
